T0 all whom it may concern.'

Be it known that I, GEORGE T. WILLrAMs, citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented vcertain new and useful Improvements in Space-Bands` for Linotype-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as willem able others `skilled in the art to which it `appertains to make and use the same, refersidered as an improvement on the construction disclosed in my `previous application, Serial No. 786,163, filed August 22nd, 1913. In said application the two space band members are independently movable on the body4 part or member, but they are interlocked 'in such a manner that a tongue of one part is movable in a groove formed between two` tongues of the other part, the last named tongues being movable in a relatively wide, dove-tailed groove formed in the body member.

In my present invention the two independently movable parts of the space band are also independently guided,-that is `to say, each member is movable `without interlocking engagement with the other member, thus diminishing the friction incident to the adjustability` of the said parts, and overcoming any possible tendency for the parts v tostick or bind during such adjustment. In a construction of this character, it is important that the space band members move v with perfect freedom, so that when the de- 1 vices which operate to lift them into their spacing position cease to act, the said parts will return by` gravity, and consequently automatically, to their normal positions.

As disclosed` in the drawing, each independently movable space band member has an independent interlocking connection with the` body part of the band.` Specifically, each member is interlocked with the body part of the band by a dove-tailed tongue and `groove connection.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof.

In this drawino,-Figu1'e l is a side elevation of a matrix lbar of the construction disclosed in my application, Serial No. 7 86,163, filed .August 22, 1913. Fig. 2 is an enlarged view of thc lower part of the flexible portion of the bar, between the two lines A and B in Fig. 1, being a view of that part of the matrix bar equipped with the space band features. This view may also be obtained by looking in the direction of arrow 2, Fig. 3. Fig. 3 is a central longitudinal section of Fig". 2,` or a section taken on the line 3-3, Fig.2. Fig. 4 is a view looking in the directionof arrow 4, Fig.` 3. Fig. 5 is a central longitudinal section of the construction shown in Figs. 2 and 4, but with one of the space band members in a different relative position. Fig. 6 is a similar view, `with the space band members in still a different position from that shown in Fig. 5. Fig. 7 is a detail view of the body part .of the space band, equipped with y a relatively short, wedge-shaped member'. Fig. 8 `is a detail view of one ofthe independently `movable space band parts. Fig. 9 is a similar view of the other independently movable part.

ico 17 is a sectional view similar` to Fig. 15, but

. 11o Re erring first toFigs. 1 to 13, inclusive, let the numeral 5 designate a matrix bar` having a flexible part 6, including a number of members 7, connected by thin metallic parts 8. The lower portion 9 of the flexible part of this bar is equipped with the space band features comprisingmy present construction. rlhe upper portion of the part 9, or' the portion which is intersected by the casting line 10, is equipped with a relatively small, stationary, wedge-shaped part 12 which carries a dove-tailed tongue 13 arranged to slide freely in a groove 14 of counterpart shape formed in an independently movable, wedge-shaped space band member 15. ranged that their thinner extremities are pointed in opposite directions, so that as the movable member 15 engages the stationary member 12, the opposite sides of the cooperating parts 12 and 15 are parallel. On the opposite side of the body part 9 from the member 15 is located a second independently movable space band part 16. This part 16 is provided with two dove-tailed tongues 17 and 18, which move in a groove 19 of counterpart shape formed in the body part 9, the construction being such that the part 16 is movable freely upon the body part 9, and independently of the part 15. The construction is also such that the part 16 and the part 15 may be arranged in cooperative relation, as best illustrated in Fig. 6, without interfering in any manner with each other, the said movable parts 15 and 16 be ing guided independently of each other and without iinzerloclrinn` relation. l/Vhen this form of construction is in use, if the wedgeshaped part 15, when arranged in coperative relation with the wedge-shaped part 12, will" perform the desired spacing function between the matrix bar members, the part 16 will-remain idle, as illustrated in Figs. 2 to 5, inclusive. When, however, the movable space band member 15 is not sufficient to give the desired spacing result, the member 16 is brought into requisition, as disclosed in Fig. 6, where the three parts 12, 15, and 16 are employed in cooperative relation at the casting line 10 to perform the spacing function.

Referring now to the form of construction shown in Figs. 14 to. 20, inclusive, let the numeral 2O designate a relatively stationary wedge-shaped space band member, which may be said to constitute the body part of the device. As illustrated in the drawing, this part 20 is thiclest at its upper extremity, and tapers downwardly. To the lower extremity of the part 2O is secured a tongue 21 which extends from one side thereof. This' tongue is of dove-tailed shape, and engages a groove 22 of corresponding shape formed in a movable wedgesh'afped spa-ce' band member 23 which is thickest at its lower extremity, and tapers gradually toward its upper extremity.

The two parts 12 and 15 are so arf This part 23 cooperates with the stationary member 2() to maintain the opposite surfaces of the two parts in parallel relation during the performance of the spacing function. lhe tongue 21 of the part 20 extends below the lower extremity of the last named part, and on the side opposite fromthe movable member 23 a dove-tailed tongue portion 24 extends, and interlocks with a groove of counterpart shape formed in a second movable space band member 26. As illustrated in the drawing, the tongue 21 is secured to the part 20 by rivets 27, while the tongue part 211 is secured to the lower portion of the tongue 21 by rivets 28. 1n describing the operation of this construction, it must be assumed that the wedgeshaped part 20 is stationary, and coperates with the movable wedge-shaped part 23, their thinner extremities pointing in opposite directions, and the two parts coperating with each other to maintain the parallelism between their opposite surfaces. When the desired word spacing function can be obtained by the adjustment of the member 23, the part 26 remains inactive. When, however, a greater spacing function is required than can be obtained by the employment of the part 23 in coperative relation with the part 20, the part 26 is brought into requisition by moving it upwardly until it crosses or intersects the castingline or area 10, which, as illustrated in the drawing,

is between the two horizontal dotted lines in Figs. 3, 5, 6, 15. and 1'?.

Attentionis called to the fact that the `member 26 is of uniform thickness except at its upper extremity, which is beveled. In adjusting this member, it is only necessary to more it a suliicient distance to cause its beveled end to pass above the casting line or area 10, since all portions below this beveled end are of uniform thickness, as just explained.

W'hereV this construction is used with the present lcommercial linotype machine, the space band operating device must be of special construction, whereby it will become practicable to aotuate the space band members independently of each other.

ln view of the fact that this application is limited to improvements in space bands, it is thought unnecessary to illustrate the space band operating device, which properly belongs to the machine mechanism. m

Attention 'is called to the fact that the body part 9, upon which the space band members are mounted, consists of a thin steel member which is sufficiently flexible to permit the space band. member 16, when in its lowermost or normal position, to pass underneath the space band member 15 when the latter is raised to intersect the casting line. This arrangement is illustrated in Fig. 3, in which the member 15 is in the lowest position which it can occupy and intersect the casting line, and in this view it will be practicable,in clamping the matrix bars for type casting purposes, to force the member 16 laterally underneath the member 15. Attention is also called to the fact that in the views of this drawing most oi' the parts are considerably exaggerated in size, in order to make the construction entirely clear.

Having thus described my invention, what I claim is:

1. A space band composed oi' a body part and two members adjustable thereon independently of each other, and non-interlocking at all times.

2. A space band composed of a relatively stationary part and two distinct members adjustable and guided thereon independently oi' each other, said `members being` continuouslymon-interlocking.

3. Aspace band composed of a relatively stationary body part and two continuouslynon-interlocking members adjustable thereon `independently of each other, each member having an independent interlocking connection with the body part for the purpose of such adjustment.

4. A space band composed of a relatively stationary body part and two continuouslynon-interlocl ing members adjustable thereon independently of each other, each member having an independent tongue and groove connection with the body part.

5. Aspace band composed of a relatively stationary body part and two continuously non-interlocking members adjustable thereon independently of each other, each member having an independent dove-tailed tongue and groove connection with the body part.

dependently of each other, said adjustable members being arranged on opposite sides oit the stationary part and guided thereon .independently of each other.

7. A space band, comprising `a relatively stationary part, and two continuously-noninterlocliing members adjustable thereon independently of each other, the two movable members being respectively wedge-shaped and of uniform thickness, and guided on the stationary part independently ol' each other during such adjustment.

9. A space band composed of a relatively stationary part having a fixed wedge-shaped enlargement intersecting the casting line, a wedge-shaped member movable on the stationary part and cooperating with the fixed wedge-shaped part, and a second member movable on the stationary part independently of the first named movable member, the two movable members being arranged on opposite sides of the stationary part, continuously-non-interlocking and guided there on independently of each other.
